GEEKOM A7 mini PC review – Part 3: Ubuntu 22.04 (and Ubuntu 24.04)

GEEKOM A7 Ubuntu 22.04 Linux review

After a GEEKOM A7 mini PC unboxing and teardown, I tested the AMD Ryzen 9 7940HS mini PC in Windows 11 Pro, but I’ll now report my experience with the GEEKOM A7 running Ubuntu 22.04.4 to see our well the AMD Ryzen 9 7940HS system performs in Linux. I also had to install Ubuntu 24.04 to check the wireless module further, so I’ll report on that too. The Ubuntu 22.04 review will include features testing, several benchmarks, storage, 2.5GbE, and WiFi 6 networking performance testing, a stress test to check thermal performance, as well as fan noise and power consumption measurements. Ubuntu 22.04 installation I resized the Windows 11 partition to get an unused 500GB partition to install Ubuntu 22.04 from a USB drive. But the first time, it did not work as I was asked to disable BitLocker disk encryption in Windows 11 just like I did for the […]

Semtech AirLink XR60 is the world’s smallest rugged 5G router

Airlink XR60 world smallest rugged 5G router

Semtech AirLink XR60 is a tiny 5G router powered by a quad-core Cortex-A53 processor with up to two Ethernet ports (1Gbps and 5 Gbps), WiFi 6 connectivity, GNSS navigation, and an optional RJ45 serial port. Semtech is better known for its LoRa low-power transceivers, but the company acquired Sierra Wireless last year, so they’ll now have a wider range of wireless products to offer, and the AirLink XR60 5G gateway is the first we cover here on CNX Software since the merger between the two companies. Semtech Airlink XR60 specifications: SoC – Quad-core Arm Cortex-A53 processor Memory – 1.2 GB RAM (that should be the free memory) Storage –  1.7 GB (available storage) Networking 5G cellular Sierra Wireless EM9291 5G NR Sub-6 M.2 module Peak downlink – 2800 Mbps Peak uplink – 300 Mbps 4×4 MIMO 4x SMA antenna connectors Dual SIM (Nano-4FF) Carrier – AT&T, FirstNet 4G, T-Mobile, Verizon, […]

Spark Analyzer is a USB-C PD analyzer and power supply based on ESP32-C3 (Crowdfunding)

spark analyzer front back

Spark Analyzer is an ESP32-C3-powered device built to streamline the process of developing and debugging USB-C Power Delivery (UCPD) solutions. The board’s design is simple, compact, and includes helpful power delivery and analysis functionality, at an affordable price. Spark Analyzer runs on an ESP32-C3FH4 microcontroller, a low-power SoC with a single-core RISC-V CPU with onboard 2.4 GHz Wi-Fi and Bluetooth 5 (Low Energy) connectivity. The wireless chip lets users control the Spark Analyzer and monitor its operation remotely. It also supports integration with other smart devices via Matter.  The device allows you to adjust voltage output from 5V to 20V, depending on your project requirements. Power is sent to a connected device via the two-pin screw terminal block on the device, and a Cross Chip sensor measures the electrical current sent through the device using Hall effect. It includes a software safety feature that turns off the output field-effect […]

52Pi P02 PCIe expansion board for Raspberry Pi 5 features a PCIe x1 slot

P02 PCIe Slot For Raspberry Pi 5

The 52Pi P02 is an expansion board for the Raspberry Pi 5 that converts the Pi’s PCIe into a PCIe x1 slot. The board gets connected to the bottom of the Pi and taps into the Pi’s power with the help of onboard pogo pins. It supports PCIe Gen2/Gen3 speeds and features a JST connector for external power input. While writing about the 52Pi NVdigi Expansion Board, I found the P02 PCIe expansion board for Raspberry Pi 5 interesting. It features a PCIe x1 slot, allowing you to install various off-the-shelf accessories like network cards, USB expansions, and more. You can even use a PCIe riser to connect a GPU with standard PC products. This isn’t the only 52Pi product we’ve covered; we’ve also looked at the 52Pi water cooling kit and the 52Pi CM4 Router Board. Feel free to check those out if you’re interested in the topic. 52Pi […]

LibreVNA open-source USB vector network analyzer (VNA) works in the 100kHz to 6GHz range

LibreVNA Open source hardware vector network analyzer vna

Jan Käberich’s LibreVNA is an open-source hardware USB vector network analyzer (VNA) based on a Spartan-6 FPGA, an STM32 microcontroller, and RF circuitry with MAX2871 and Si5351C chips. The open-source VNA supports two channels and works in the 100kHz to 6GHz frequency range. Vector network analyzers are expensive pieces of electronic test equipment used to measure the magnitude and phase of high-frequency electrical networks costing several thousand dollars. They are commonly used in radio frequency (RF) and microwave engineering applications. Last year, we wrote that Pico Technology released PicoVNA 5 software for Linux, Raspberry Pi, and macOS instead of only providing a Windows program for their commercial PicoVNA devices. I thought it was already a good development even if it was closed-sourced, but LibreVNA goes all the way with an open-source hardware design with hardware design files, the FPGA code, STM32 firmware, and PC software (GUI) all open-source. LivreVNA hardware […]

$166 Mustool MT13S thermal imager doubles as multimeter

Mustool MT13S 2-In-1 Thermal Imager Multimeter

Mustool MT13S is a relatively inexpensive 2-in-1 thermal imager and multimeter with a 2.8-inch touchscreen display and an IR camera with a 192×192 resolution. Thermal cameras used to be quite expensive, but in recent years, we’ve seen cheaper models such as the HT-102 thermal camera for Android smartphones and M5Stack T-Lite Wi-Fi thermal camera, but those integrate fairly small 32×32 and 32×24 pixels IR arrays, The Mustool MT13S provides a higher resolution 192×192 thermal camera and doubles as a 10,000-count multimeter for about $166 plus shipping on Banggood or around $177 including shipping on Aliexpress. Mustool MT13S specifications: Thermal imaging Sensor – Uncooled focal plane Image capture frequency – 20Hz Thermal imaging resolution – 192 x 192 Display image resolution – 240 x 240 Field of view (FoV) – 50.0(H) × 50(V)/72.1(D) Emissivity – 0.1-0.99 is tunable and 0.95 is the default Temperature Range – -20°C to +550°C Accuracy – […]

STMicro ST60A3H0 and ST60A3H1 60 GHz transceiver ICs aim to replace USB cables

ST60A3H0 ST60A3H1 60 GHz transceivers

STMicro ST60A3H0 and ST60A3H1 are short-range 60 GHz transceiver ICs that tunnel eUSB2, I2C, SPI, UART, and GPIO signals and aim to replace USB and other cables in consumer devices such as digital cameras, wearables, portable hard drives, and small gaming terminals. They should also find their way into industrial applications such as rotating machinery where cable use may be challenging. The smaller ST60A3H0 chip provides more flexibility and requires an external antenna, while the ST60A3H1 chip is a fully integrated solution with a built-in linear antenna. Both are capable of USB 2.0 speeds of up to 480 Mbps and support UART, GPIO, and/or I2C signals so they are not limited to USB cables and can be used in a range of applications. ST60A3H0 and ST60A3H1 key features and specifications: 60 GHz V-Band transceiver for short-range contactless connectivity up to 480 Mbit/s eUSB2, UART, GPIO, or I2C RF tunneling Low […]

Waveshare R7FA4 PLUS A and B boards are clones of the Arduino UNO R4 Minima and WiFi

Arduino UNO R4 WiFi clone

Arduino board clones have been around for many years, but I don’t think I have ever seen clones of the new Renesas-based Arduino boards so far. Waveshare changes that with the R7FA4 PLUS A that clones with Arduino UNO R4 Minima, and the R7FA4 PLUS B board duplicating the Arduino UNO R4 WiFi. The Waveshare boards are not 100% clones with some small differences in the PCB layout, support for 5V and 3.3V shields, an additional 6-pin “power output header” with 5V, 3.3V, and GND signals, and a USB communication jumper to select between the Espressif ESP32-S3 and Renesas RA4M1 microcontrollers. Waveshare R7FA4 PLUS A and B specifications: Microcontroller – Renesas RA4M1 Arm Cortex-M4F MCU @ 48 MHz with 32KB SRAM, 256KB flash Wireless (B model only) – ESP32-S3-MINI-1 module based on ESP32-S3 dual-core Xtensa LX7 microcontroller with 512KB SRAM, 384KB ROM, WiFi 4 and Bluetooth 5.0 connectivity, PCB antenna […]
